This figure shows the volcanic peak Idunn Mons in the Imdr Regio area of Venus. The topographic backbone (brown color) was derived from data obtained by NASA's Magellan spacecraft and the overlay was derived from data from ESA's Venus Express Spacecraft.

The images used for the base of this globe show the northern and southern hemispheres of Venus as revealed by more than a decade of radar investigations culminating in the 1990-1994 NASA Magellan mission.

Venus Cloud Tops Viewed by Hubble. This is a NASA Hubble Space Telescope ultraviolet-light image of the planet Venus, taken on January 24 1995, when Venus was at a distance of 70.6 million miles (113.6 million kilometers) from Earth.

This perspective view of Venus, generated by computer from NASA's Magellan data and color-coded with emissivity, shows part of the lowland plains in Sedna Planitia. Circular depressions with associated fracture patterns, called 'coronae.'

This perspective view of Venus, generated by computer from NASA's Magellan data and color-coded with emissivity, shows the boundary between the lowland plains and characteristic Venusian highland terrain in Ovda Region.

This perspective view of Venus, generated by computer from NASA's Magellan data and color-coded with emissivity, shows part of the lowlands to the north of Ovda Regio. The prominent topographic feature is a shield volcano.

This perspective view of Venus, generated by computer from NASA's Magellan data and color-coded with emissivity, shows part of Sedna Planitia and illustrates a common phenomenon of the lowland plains of Venus.

The view from NASA's Magellan spacecraft shows most of Galindo (V-40) quadrangle looking east; Atete Corona, in the foreground, is a 600-km-long and about 450-km-wide, circular volcano-tectonic feature.

The view from NASA's Magellan spacecraft shows part of Galindo (V40) quadrangle looking north; Nagavonyi Corona is in the foreground. Coronae are roughly circular, volcanic features believed to form over hot upwellings of magma within the Venusian mantle.

A portion of Alpha Regio is displayed in this three-dimensional perspective view of the surface of Venus from NASA's Magellan spacecraft. In 1963, Alpha Regio was the first feature on Venus to be identified from Earth-based radar.
